Kensington Runestone

In 1577, cartographer Gerardus Mercator wrote a letter containing the only detailed description of the contents of a geographical text about the Arctic region of the Atlantic, possibly written over two centuries earlier by one Jacob Cnoyen. Cnoyen had learned that in 1364, eight men had returned to Norway from the Arctic islands, one of whom, a priest, provided the King of Norway with a great deal of geographical information.[19] Books by scholars such as Carl Christian Rafn early in the 19th century revealed hints of reality behind this tale. A priest named Ivar Bardarsson, who had previously been based in Greenland, did turn up in Norwegian records from 1364 onward and copies of his geographical description of Greenland still survive. Furthermore, in 1354, King Magnus Eriksson of Sweden and Norway had issued a letter appointing a law officer named Paul Knutsson as leader of an expedition to the colony of Greenland, to investigate reports that the population was turning away from Christian culture.[20] Another of the documents reprinted by the 19th century scholars was a scholarly attempt by Icelandic Bishop Gisli Oddsson, in 1637, to compile a history of the Arctic colonies. He dated the Greenlanders' fall away from Christianity to 1342, and claimed that they had turned instead to America. Supporters of a 14th century origin for the Kensington runestone argue that Knutson may therefore have travelled beyond Greenland to North America, in search of renegade Greenlanders, most of his expedition being killed in Minnesota and leaving just the eight voyagers to return to Norway.[21]
